Q: If I commit a major sin again, after repenting and making Hajj,  

     does that mean my Hajj wasn’t accepted?

Allah has blessed me with making Hajj this year after a long string of sins, and I resolved to make a real new start. But, unfortunately, I committed a major sin and I have been practically choking to death (with regret) since I committed this sin. Does that mean that my Hajj was not accepted and is there any relation between committing this sin after the Hajj and the validity

of my Hajj?
